This class represents the configuration data space of ZTEX FPGA Boards that support it.
The internal format is
<pre>
<Address> <Description>
0..2 Signature "CD0"
3 Kind of FPGA Board, see <A HREF="../ztex/ConfigData.html#boardNames"><CODE>boardNames</CODE></A>, e.g. 2 for "ZTEX USB-FPGA Module",
4 FPGA Board series, e.g. 2
5 FPGA Board number (number behind the dot), e.g. 16
6..7 FPGA Board variant (letter), e.g. "b"
8..9 FPGA, see <A HREF="../ztex/ConfigData.html#fpgas"><CODE>fpgas</CODE></A>, e.g. 12 for X7A200T
10 FPGA package, see <A HREF="../ztex/ConfigData.html#packages"><CODE>packages</CODE></A>, e.g. 3 for FBG484
11..13 Speed grade + temperature range, e.g. "2C"
14 RAM size, format is ( n & 0xf0 ) << ( (n & 0xf) + 16 ) bytes
15 RAM type, see <A HREF="../ztex/ConfigData.html#ramTypes"><CODE>ramTypes</CODE></A>
16..25 Serial number, overwrites SN_STRING of the ZTEX descriptor.
If it is equal to "0000000000" (default) it is replaced by the unique MAC address.
26..27 Actual size of Bitstream in 4K sectors; 0 means Bitstream disabled (default)
28..29 Maximum size of Bitstream in 4K sectors; 0 means that either no Flash
is present or that this information is stored in Flash (exchangeable media)
30..79 Reserved
80..127 48 bytes user space
